substantially the same altitude and in the same relation to the stamping head of the machine. Such a work support, separately considered, forms the subject-matter of United States Letter Patent No. 1,022,412, grantedl Aprilv 9, 1912, on divisional applcation Serial No. 526,395-ti1ed November 5, 1909, but its use in combination with 'the automatic releasing" device, above-mentioned, presents many advantageous and novel features and the combination is, therefore, within the ,scope of the present application. One of the advantages arisin from the lcombination of the automatic re easing device with the novel work support is that the operator is thereby enabled with one hand to set the turretwhile with the other hand the work support may be adjusted in accordance with the marking die just brought into position.

Another feature of this invention consists in the construction and arrangement ofthe turret and the means associated therewith for automatically unlocking it after each impression stroke. VAs herein shown this mechanism comprises the usual locking plunger cooperating with recesses in the turret and means to retract the plunger at a predetermined point in the stroke oftheturret suchv means being located upon a convenient part of the machine frame and operating to retract the plunger as theturret reaches a certain point in its stroke, hold the plunger retracted for a definite period, during which the turret may be'turned and a new stamp may be set, and release it at the proper time whereby the turret is again locked.

As herein shown the locking plunger is forked at its outer end and carries a transverse pin extending between the two forked portions thereof. A fixed arm provided 95 with a plunger retracting member mounted on its lower end projects downwardly from T0 all 'whom it may concern:

Be it known that I, JoHN J. GILLESPIE, a citizen of the United States, residing at Boston, in the county of Suffolk and bom monwealth of Massachusetts, have invented certain Improvements in Stamping- Machines, of which the following description, in connection with the accompanying drawings, is a specification, like referencecharacters on the drawings indicating like parts in the several figures.

This invention relates to prees and other machines for operating upon shoes and other articles and it is herein shown as embodied in a shoe stamping machine. These machines are employed for stamping trade or other marks upon the bottoms o shoes.

to stamp the shoe bottom in a plurality of places-as, for example, to stamp a trademark or name upon the tread face of they heel and a rice or other mark upon the tread face o the shank or other portion of the sole. It is, therefore, frequently necessary to change from one marking'die to another in operatin on a single shoe and in this operationmuci time is lost, particularly where it is necessary for the operator to employ both hands in bringing a new die into stamping iosition. -Heretofore it has been the ractice to mount av number of marking dies in a rotatable turret carried in a reciprocattog7 head and to. provide a spring actua plunger for locking the turret with one or other of the dies in the stamping position. This arrangement makes it necessary for the operator to use one hand for-retracting the locking plunger and the other to turn the turret so as to bring the desired die into position.

With these conditions in view it is an object of-the resent invention to provide an automatic evice for releasing the turret during a convenient interval in the cycle of the stamping machine and so afford the o Irator opportunity to set a new die in )llico with one hand while the other isleft lfree for the manipulation of the shoe being operated upon. Such an arrangement 1s particularly advantageous in connection with a novel work supporting device having provision for ad'ustment through detinte predetermined ,istancee so as to sup- .port either the heel or the sole of a vshoe at' the machine frame between the forks of the plunger and inside the transverse pin,`in

such a position that the plunger retracting member is normally projected into the path of the transverse pin as the plunger and turret are reciprocated.

When the turret is lowered for the im' Eression stroke the plunger retracting mem- 106 jr is forced back and permits the pin to pass but when the turret is raised the pin engages the plunger retracting member and forces it out, being itself at the same time moved outwardly by the coaction between the two, thus drawing the plunger out of engagement` with its recess and permitting the turret to be set in a new position. In solne cases it is found that the automatic means for unlocking the turret does not allow the operator sufficient time to set a new stamp and accordingly a releasing device has been devised which is designed to be operated by a treadle. One of the machines in which it is intended to use this releasing device is arranged to make a complete stroke and then stop with the turret in its highest position. The treadle actuated releasing means are, accordingly, so located that at the top of the stroke there exists an operative relation between the different members so that the tui-ret can be unlocked at this point andret-carrying head comprise a plunger re-.

tracting member mounted on the machine frame to permit of a limited motion under the actuation of the treadle and a locking plunger moving with the turret and carried therewith into operative relation with the treadle actuated'plunger retractin'g member. More specifically this releasing device comprises a lever pivoted on the machine frame, adapted to be actuated by the treadle and having formed thereon a wedge shaped cam surface, and mounted on the turret-- carrying head is the usual locking' plunger, shouldered toward the turret for engagement with the Wedge cam whereby a downward motion of the lever retracts the plunger and leaves the turret free for vadjustment. The manually actuated releasing device just described is designed for use either as supplementary to the automatic releasing neansvand operating on the same locking plunger or the automatic releasing means may be dispensed with and the manual releasing means used alone. T he combination of the two results in a convenient machine adapted for eiicient use by either a fast or slow operator. A novel means for holding the stamps in the turret has also been pro-' vided which consists broadly of a draw bolt adapted toclamp the shank of the stamp within the body of the turret. A hole is drilled into the face of the turret so as t0 intersect each of the radial openingsV for the Shanks of the stamps and pass through one Side thereof.V The draw bolt is provided with a recess so located that when the bolt is in its extreme inner osition the sides of the recess exactly coinci e .with the walls of the opening for the shank, forming a continuous` surface therewith. The outer end of the bolt is screw threaded and provided with a nut which draws out on the 0f the turret. In the old form of machine Fig. 7 is a detail of the same.

in which the shanks of the stamps were screwed into the body of the turret a whole turret was often made useless by stripping the thread of one stamp whereas in -the improved form there is no liability of damaging the turret.

These-and other features of the invention, including certain details of construction and arrangements of parts, `will be explained in connection with thel following description of a preferred embodiment of the invention and will be pointed out in the claims.

In the drawings: Figure 1 is a side elevation of a bottom stamping machine embodying the present invention. This machine is in its general construction and operation essentially similar to a machine shown in United States Letters Patent No. 1,028,567, granted June 4, 1912 on an ap,- plication filed by Gordon and Topham Serial No. 186,368. Fig. 2 is a section on approximately the line 2 2 of Fig. 4. Fig. 3 is a perspective view of the shoe supporting means. Figs. 4 and 5 show the shoe supporting means and the stamp in different adjusted positions for marking the heel and sole of a shoe, respectively. Fig. G is a perspective view of the turret and the means associated therewith for automatically unlocking it after each impression stroke. Fig. 8 is a fragmentary section on the line 8--8 of Fig. 6 showing lneans for holding the stamps in the turret. Fig. 9 is a perspective view of a turret releasing device which can be used as a supplement to or independently of the means shown in Fig. 6.

The machine comprises a wheel 2 adapted to carry a plurality of stamps 3, 4 for the heel and sole, respectively, together with suitable means l for actuating the wheel toward the Work-supporting means located below it. The work-supporting means comprises, in accordance with one embodiment of this invention, a base 5 adapted to rest upon a post 6 land sustaining means therefor, which may be like that shown in said patent last mentioned and adapted to yield for slight variations in the thickness of the work or it may be of any other suitable type. The base 5 has, at one side of the line of pressure applied by the stamp, ears 7 between which is pivoted a laterally projecting arm 8 from a spindle (guide 10 in which the Work-supporting spin le 12 is arranged for adjustment. A plvot pin 15 projects upwardly from the base and holds 1n assembled relation a plurality of-superposed blocks 16 adapted to swing from and toward a position in alinement with or vertically under the spindle 12 where they form auxiliary rests for the spindle. Each of these blocks is provided with a spring-pressed plunger 18 adapted to bear on one or the other of the two beveled surfacesl) and 20 of the pin 15.l These plungers, engaging and beveled faces of the pin, hold the swinging blocks normally in one or the other of two definite positions and when a block is moved slightly peet the center in one or the other direction the plungers will continue that movement and force the block fully to the definite position which it is approaching. Each block exce t the bottom one is provided with a depen ing stud indicated vat 22 adapted to engage a recess 23 in the adjacent face of the next lower block. The recesses are so shaped that when any block except the last block is turned from its inoperative sition toward its operative or spindle-raising position all the blocks below it are also compelled to turn in that direction. When any of the blocks are engaged and turned toward inoperative position all the blocks above it are compelled to move with the block to which the turning force is applied. Limiting studs 24, 26 are arranged to stop the lower block in its two positions and the engagement of the pins 22 in the recesses 23 causes the other blocks to be stopped in alinement with the bottom block. he blocks or part of them are or may be proportioned in thickness to the standard heights of heels so that different groups of them will produce different adjustments in the height of the spindle according to the standard height of the heel on the shoes being stamped. The number of the blocks and the thickness or relative thickness of the several parts may be varied as conditions may require.

In the use of the invention the shoe may be applied to the spindle as indicated in Fig. 4 for stamping the tread face of the heel. Then, while the stam -carrying turret is raised' the spindle wit its guide may be tipped, as shown in Fi 3, to raise the spindle and give access to t blocks, whereupon the operator will engage as many o blocks as are r uired to compensate for the difference in thickness of the sole and the particular heel of the shoe being stamped and will swing those blocks into their operative position under the spindle. The spindle guide will then be tipped back to its upright position and in this movement the spindle, after contacting with the upper face of the top block in operative position, will be raised to elevate the work to the altitude in which the tread face of they sole to be stamped is in the same or substantially the same relation to the stamp as was the tread face of the-heel. In shifting the blocks toward their operative position it is only necessary to engage the top of the blocks which it is desired to use, because the pins 22 compel each of the blocks below the top one to move with that one. It is unnecessary for the operator to restrain the upper blocks lber projecting into the l from moving because the spring plungers 18 by their engagement with the inclined face of the pin 15 holds those blocks from movement. Similarly when moving the blocks to their inoperative position it 1s only necessary to engage the lowest block which is to be turned and all the others are compelled to turn with it.

In Fig. 6 is shown the turret 2 carrying the various stamps 3 and-provided in one side with a series of recesses 28, onev recess corresponding with each stamp, and with these recesses there coperates the locking plunger 27 properly hushed and slidingly mounted in one arm of the turret-carrying head 9, the inner end of the locking plunger and the recesses being correspondingly tapered. The locking plunger 27 is normally urged toward the turret by the spring 13 to enter one of the recesses and thus hold the corresponding stamp in the proper position for stamping. On the outer end of the locking plunger 27 is mounted, in any suitable manner, the forked member 29 carrying between the outer ends of its fork the transverse pin 30. Mounted upon a convenient stationary part of the machine is the downwardly projecting arm 26 having a reduced portion arranged to slide freely between the forks of the member 29 as the turret and locking mechanism are reciprocated. This arm at its lower end is provided with a slot in which is pivotally mounted the wedge shaped cam member 31, the pivot being approximately at its vertex, as shown and a spring 32 tending normally to hold the Wedge shaped memthe path of thel transverse pin 30 It will be apparent from inspection of Fig. 7 that as the turret is lowered carrying with it the locking mechanism the pin 30 will ride down the inclined face of the wedge 31 and then the wedge ywill yield into its slot thus permitting the pin to pass without being detiected from its path orY disturbing the locking plunger 27. On the other hand, when the turret is moving away from the work and the pin 30 travels upwardly it engages the lower face of the Wedge 31 swinging it outwardly about its pivot, as shown by the dotted lines in Fig. 7, and moving with it away .from the turret thus withdrawing the lookin plunger 27 and leavin",l the turret free to turned by the operator. At the upper limit of the stroke thepin 30 slides off the wedge shaped. member above it and the plunger 27 is returned to engage the turret. By varying the proportions slightly it is sometimes expedient to prevent this inal disengagement of plunger and wedge shaped member so that the plunger is held retracted at the upper limit of the stroke and the turret left free to turn until the machine is again started when on the downward motion of the turret' the plunger will again perform its function.

In Fig. 9 is shown a form of turret releasing device which is adapted to be operated by means of a treadle, when, for any reason more time is desired to set the turret than is allowed by the automatic releasing device described above. In this construction a portion of the plunger 27 is reduced 1n diameter forming the shoulder 33 with which cooperates the forked wedge shaped cam 34, formed on a lever 35 pivot-,ed at one end by a pin 40 to a stationary arm 2G which latter is carried by a suitable part of the machine frame. At its outer end the lever 35 is connected through a link 38 to the treadle 39 and a spring 37 is provided which normally holds the treadle and lever in their upper position. In this construction the turret is released in its upper position by the operator when the treadle is depressed, the lever 35 and thc wedge cam 34 carried thereby moving downwardly so -that the wedge faces of the forked cam 34 retract the locking plunger 27. This leaves the turret free to turn so long as the treadle is depressed and the turret remains in its upper position while on releasing the treadle, the spring 37 instantly disengages the cam 34 from the shoulder 33 allowing the plunger to lock the turret. In Fig. S) the turret carrying plunger 5) is represented as in its upper position, the plunger and wedge cam being in operative relation. lt will be clear that when the turret. starts to move downwardly for the impression stroke the plunger 27 will move beyond the reach of the wedge cam 34, or out of engagement therewith if the treadle is depressed, so that there is no possibility of a stamp reaching the work while the turret is unlocked even if the operator forgets to release the treadle.v As already stated the manually operated releasing device may be used with leasing means shown in Fig.

'lhe improved means for holding the stamps in the turret is illustrated in Fig. 8 where 3 represents the shank of one of the stamps 3 set in a radially drilled hole in the turret 2. Bolt holes in this case, but not necessarily, coinciding with the locking reeesses Q8, are drilled into the side of the turret so as to intersect each radial shank hole and pass through one side thereof. Each draw holt 50 is provided with a recess 5l on one4 side so located that when the bolt is in its extreme inner position the sides of the recess exactly coincide with the walls of the radial shank hole and the stamp may be withdrawn or inserted without obstruction. The outer end of each draw bolt is threaded and provided with a nut 52 by which the recess in the bolt may be drawn or without the automatic reslightly out of line with radial shank hole, thereby locking the shank of a stamp firmly in the turret.
